IMPROVEMENT IN BABV-JUMPERS.

Specification forming part of Letters Patent No. 166,845, dated August17, 1875; application filed January 25, 1875.

To all whom it may concern Be it known that I, ROBERT W. CALDWELL, ofZanesville, in the county of Muskingum and State of Ohio, have inventedcertain new and useful Improvements in Baby-Jumpers; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had tothe accompanying drawing and to theletters of reference marked thereon.

The nature of my invention consists in the construction and arrangementof a babyjumper, provided with an interchangeable crib or cradle andhobby-horse, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a side elevation of my invention when used with the crib orcradle. Fig. 2 is a similar view, part in section, of my invention whenused with the hobby-horse. Fig. 3' is a plan view of the base thereof.

N represents the base of my baby-jumper, made in the form of a cross, asshown in Fig. 3. The front end M of the base is widened,

as shown, for the attachment of the C-shaped' springs G G. On the rearend of the base N is secured a spring, R, to catch and return thedownward motion of the crib or hobby-horse used. The springs G G may bemade in the form shown, or in any suitable shape to secure the verticalmotion, and to their upper ends is fastened a bar, E, having alongitudinal slot, F, as shown. A represents the crib, provided on itsunder side with a suitable loop, S, to pass over the bar E, and the cribis adjusted and held on said bar by means of a clamping device, 3passing through the slot F, so that the crib can be adjusted to suit theweight of the baby to be placed therein. The front end of the bar E isprovided with a footrest, I, made in any suitable shape for rocking thebaby.

I have constructed a hobby-horse, B Z, to be used upon the spring-bar Eafter detaching the crib. The base or extended bottom D of the chair Bis provided with a pommel, V, to prevent the baby from sliding out ofthe chair. The hobby-horse is adjusted to the bar E in the requiredposition by a clamping device in the same manner as the crib.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. The combination of the base N, springs G G, slotted bar E, foot-restI, and spring R, substantially as and for the purposes herein set forth.

2. The hobby-horse Z, base D, pommel V, chair B, and clamping device y,substantially as and for the purposes herein set forth.

3. The combination of the base N with its flat widened surface end M,springs G G and R, foot-rest I, crib A, loop S, clamping device 3 andslotted bar E, substantially as and for the purposes herein set forth.

4. The combination of the hobby-horse Z, base or bottom D, pommel V,chair B, clamping device 3 and the slotted spring-bar E, connected tothe base M N, all substantially as and for the purposes herein setforth.

In testimony that I claim the foregoing I have hereunto set my hand this23d day of December, 1874..
